Diy Solar Charge Controller Arduino

This design is suitable for a 50w solar panel to charge a commonly used 12v lead acid battery.

Diy solar charge controller arduino.

The microcontroller used is in this controller is arduino nano. The output voltage of the voltage divides is one sixth 16 of the input voltage. The input to tp4056 can be in the range of 4v to 8v which is the range of the output of the solar panel. The amount of charging current is determined by the difference between battery voltage and charge setpoint voltages.

It is very strong and durable but it always works silently. Nowadays the most advance solar charge controller available in the market is maximum power point tracking mppt. Do not forget to install all the necessary libraries before uploading the code to arduino nano. Simple mppt maximum power point tracking solar charge controller for 18v solar panels.

In india most of the people are living in rural areas 400 million people that are currently have no access to electricity despite india being the world s 5th largest energy producer the existing electric grids are not capable of supplying the electricity need to those poor people. You can also use other arduino board like pro mini micro and uno. An arduino based solar mppt charge controller. The heart of the charge controller is arduino nano board.

The arduino mcu senses the solar panel and battery voltages. This is an atmega32u4 based synchronous mppt buck solar charge controller. Howtomakesolarchargecontroller solarpannel chargecontroller this video will show you how to build a home made solar charge controller featuring. 1 10 arduino based mppt solar charge controller download source code.

Tp4056 then charges the battery from the solar power itself. In the above picture there is typographical error in power and control signal. Proper buck converter topology which increases the current on the output side not just pwm. According to these voltages it decides how to charge the battery and control the load.

The voltage divider network r1 and r2 are used to scale down the voltage provided by the solar panel vpv so that the maximum voltage supplied to the arduino analog input a0 doesn t exceed it the maximum voltage limit which is 5v. I can not kn. Programmable with arduino ide. According to these voltage levels it decides how to charge the battery and control the load.
